Abstract

The invention provides a bucket arm cylinder control system, a control method and an excavator, and relates to the technical field of engineering machinery. The bucket arm cylinder control system involves a bucket arm cylinder, flow control parts, a pressure sensor and a controller, wherein the flow control parts and the pressure sensor are connected with the controller; and the flow control partsare arranged on an oil inlet path of the bucket arm cylinder, the pressure sensor is used for detecting pressure data in a large cavity of the bucket arm cylinder and transmitting the pressure data to the controller, and the controller receives the pressure data and controls the flow of the flow control parts according to preset data. Through the bucket arm cylinder control system, the technicalproblem of the energy waste existing in an excavator in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a stick cylinder control system, a control method and an excavator. Background technique [0002] With the vigorous development of infrastructure, more and more excavators are used in our country, which also brings more economic value to customers. [0003] An excavator, also known as an excavating machine or a backhoe, is an earth-moving machine that uses a bucket to dig materials higher or lower than the bearing surface, and loads them into transport vehicles or unloads them to the stockyard. The materials excavated by the excavator mainly include soil, coal, sediment, and pre-loose soil and rock. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast, and excavators have become one of the most important construction machinery in engineering construction. [0004] However, in the actual use of th...
